It depends on what app you are using. I don't see the search icon too, because I am using the app downloaded from Indian playstore, and this app doesn't have that features. Even if the website has, it depends on the app. If you have downloaded from the American playstore, then it may show you that option. If your country's app doesn't allow, then you can try using a VPN to download the foreign version of app. Also, you can download apk file.
